Let see if I can confuse you a little bit. OAuth, pronounced “Oh Auth”, started as OpenAuth – OpenID’s party-loving cousin. AOL came and took OpenAuth for their own API protocol. It then changed to Oauth pronounced like “Oath” until Pownce’s Leah Culver talked everyone into the current pronunciation (or so the legend goes). Now, OAuth has nothing to do with OATH, the Initiative for Open Authentication over at OpenAuthentication. And if an Israeli tries to explain OAuth to you calling it “Oh Oaf”, don’t take it personally.
